  • Publication number: 20180261665
    Abstract: A thin film capacitor in a redistribution layer of a semiconductor device including a semiconductor chip. The thin film capacitor includes a capacitor body including a first electrode, a dielectric on the first electrode, and a second electrode on the dielectric, and an adhesive portion disposed on a lower surface of the first electrode and used for attaching the thin film capacitor to a protective film of the semiconductor chip. A total of a thickness of the capacitor body and a thickness of the adhesive portion is 20 ?m or smaller.

  • Patent number: 7472773
    Abstract: An electrically driven power steering apparatus is structured such that a large impact on a rack shaft occurs upon an impingement of a steering stopper, and, even when an axial force acting on a ball bearing of a presser member becomes zero, a rotation of the presser member is hindered by caulking c at a thin plate member. Therefore, the presser member does not slacken, and a predetermined axial force can be given again to the ball bearing when the impact dissipates. The thus structured power steering apparatus exhibiting, though the cost is low, an excellent shockproof characteristic and capable of preventing the bearing from coming off a ball screw nut, can be provided.

  • Patent number: 6851508
    Abstract: An electrically driven power steering apparatus is structured such that a large impact on a rack shaft (22) occurs upon an impingement of a steering stopper, and, even when an axial force acting on a ball bearing (25) of a presser member (30) becomes zero, a rotation of the presser member (30) is hindered by caulking c at a thin plate member (30b). Therefore, the presser member (30) does not slacken, and a predetermined axial force can be given again to the ball bearing (25) when the impact dissipates. The thus structured power steering apparatus exhibiting, though the cost is low, an excellent shockproof characteristic and capable of preventing the bearing from coming off a ball screw nut, can be provided.
